Synergy effect modelling of cavitation and hard particle erosion: implementation and validation [PDF]

, 2021
The prediction of the wear behaviour of components under conditions of cavitation and hard particle erosion requires the implementation of a new model capable of accounting for the accelerated damage due to the synergic effect of both phenomena.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion
